SUPPORT VECTOR MACHINE LEARNING SYSTEM AND SUPPORT VECTOR MACHINE LEARNING METHOD

摘要

[Problem] To make it possible to reliably conceal a label of a supervisory signal when support vector machine learning is performed.;[Solution] An analysis executing apparatus that performs support vector machine learning, stores a set of learning data including a feature vector and a label encrypted using an additive homomorphic encryption scheme, which are subjected to the support vector machine learning, and performs update processing with a gradient method on the encrypted learning data using an additive homomorphic addition algorithm.
